Definitions

  • the present invention relates to a gap seal system having an automatic adjustment of the gap between a resting component and a moving component, or components that move relative to one another.
  • the components form a common cavity for transfer of a medium between a control valve and a vacuum roller for transporting cut-outs via vacuum.
  • this technology is used at many locations in the production process to supply a vacuum roller for transporting envelope cutouts or material webs with vacuum.
  • the vacuum roller which is mounted in a machine frame, is supplied with vacuum by a control valve mounted on the roller axle.
  • the control valve is axially displaceable to adjust the gap between vacuum roller and control valve, and radially displaceable to adjust the bezel position.
  • the disk cam is moved on the axle, using an adjustment nut that can be fixed in place towards the face of the vacuum roller, against a spring package, until the smallest possible gap is adjusted. Subsequently, the control valve is fixed in place axially and radially relative to the machine frame. The gap width must be checked using a gage, and must not be too small, so that seizing of the sealing surfaces is precluded.
  • the vacuum runs to the vacuum air channels that lie crosswise in the vacuum roller by way of the disk cam, and from there to the vacuum air openings that are distributed on the circumference, in accordance with the requirements, in each instance.
  • the vacuum roller can also be provided with vacuum section by section, or also can supply certain sections with blowing air, by means of a second chamber in the disk cam.
  • One embodiment of the device according to the invention has a control valve that supplies the vacuum air bores at the circumference of a vacuum roller with vacuum and/or compressed air, by way of the cross-bores in the vacuum roller, and of an adjustment device.
  • a disk cam is preferably still affixed to the vacuum roller that is mounted to rotate in the machine frame, in order to be able to utilize the vacuum roller for different format settings.
  • control valve is rigidly attached to the machine frame and structured in such a manner that it is able to supply the vacuum roller with vacuum and/or compressed air over a specific angle range, by means of the disk cam.
  • the disk cam can consist of several partial segments, with at least one connection for vacuum or compressed air, in each instance.
  • the two parallel sealing surfaces of the vacuum roller, or of the vacuum roller with the disk cam, and of the control valve are pressed against one another and fixed in place, by means of the adjustment device, with the desired force.
  • the adjustment takes place via an adjustable adjustment nut on the axle, which can be fixed in place and can move the axle mounted in the machine frame, with the vacuum roller attached to it, axially against a spring package.
  • the vacuum roller may be fixed in place in its position, and the disk cam may be movable, so that it can be adjusted and fixed in place relative to the frame, for example by way of tension/pressure screws.
  • one of the sealing surfaces has a hard and rough surface, preferably the sealing surfaces of the vacuum roller, and the other consists of a material that can be worked by the hard, rough surface.
  • the hard, rough surface can be, for example, a coating, or the roughness can be produced by sand-blasting.
  • Graphite or plastic for example, can be used as the counter-material. It is particularly advantageous if the disk cam itself does not consist of the counter-material, but rather is equipped with an interchangeable sealing surface.
  • a labyrinth seal effect can advantageously be achieved, in order to minimize the leakage current.
  • the hard sealing surface may be smooth and the soft sealing surface may be rough, so that when the vacuum roller starts up, the peaks of the soft sealing surface wear down, until there is no longer any contact.
  • Another advantage of the device is the protection against seizing, if the components expand because they have been overheated, because only the seal gap increases and this can subsequently be readjusted again in a simple manner.
  • FIG. 1 shows a side view of one embodiment of the device according to the invention
  • FIG. 2 shows a control valve according to an embodiment of the invention
  • FIG. 3 shows a configuration example for the sealing surface according to the invention
  • the embodiment of the device according to the invention, for producing a self-adjusting gap seal, described below, can be used, for example, for the vacuum supply ( 6 ) of vacuum rollers ( 1 ) for the transport of a cutout as they are used in the production of envelopes.
  • FIG. 1 shows one embodiment of the device according to the invention in a side view.
  • disk cam 4 is attached to vacuum roller 1 .
  • Disc cam 4 former possesses a hard, rough sealing surface 10 that can work a material that wears easily, for example graphite.
  • Disk cam 4 has a bore image that is coordinated with the desired application, so that only the desired part of vacuum bores 3 , in each instance, is connected with vacuum 6 by way of cross-bores 2 in vacuum roller 1 .
  • Vacuum roller 1 with disk cam 4 attached to it is mounted in the machine frame so as to rotate and be axially displaceable.
  • Control valve 5 is rigidly connected with the machine frame.
  • the sealing surface of control valve 5 consists of a material that wears easily, such as graphite, for example.
  • the hard, rough sealing surface 10 of disk cam 4 is brought into contact with sealing surface 11 of control valve 5 by means of the adjustment device that consists of adjustment nut 8 on axle 14 and spring package 12 . This takes place before start-up of vacuum roller 1 , whereby contact pressure is selected in accordance with the desired amount of wear.
  • sealing surface 10 of disk cam 4 grinds sealing surface 11 of control valve 5 down to a point that there is no longer any contact between sealing surfaces 10 , 11 , and therefore the smallest possible gap dimension has been formed.
  • the chips that are formed in this connection are vacuumed away by vacuum 6 .
  • FIG. 2 shows a control valve 5 in an exemplary embodiment.
  • Control valve 5 has two segment sections that can be supplied with vacuum 6 or compressed air, independently of one another.
  • FIG. 3 shows possible embodiments of the working sealing surface, as examples:
